Abstract
The architecture of a device that is optimized for wireless
information access and display of multimedia data is substantially
different than configurations designed for portable stand-alone
operation. The requirements to reduce the weight and energy consumption
are the same, but the availability of the wireless link, which is needed
for the information access, allows utilization of remote resources. A
limiting case is when the only computation that is provided in the
portable terminal supports the wireless links or the I/O interfaces, and
it is this extreme position that is explored in the InfoPad terminal
design. The architecture of the InfoPad terminal, therefore, can be
viewed as essentially a switch which connects multimedia data sources in
the supporting wired network to appropriate InfoPad output devices
(e.g., video display), and connects InfoPad input devices to remote
processing (e.g., speech recognizer server) in the backbone
network
